Title: Fixes in test transport and others #3099

Several fixes here:
- TestTransport does not rely anymore on broken assumption about onComplete ordering
- ThrottlerTransportAdapter now correctly relays backpressure from lower layer
- AkkaProtocolTransport retries initial write of ASSOCIATION message in case of backpressure

Potentially fixes: #3032, #3045, #2930
